[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model provides Figure 1-5An exhaust valve assembly is shown, comprising an outer shell 1, an air inlet pipe 2 is fixedly provided at the lower end of the outer shell 1, an inner bin 7 is fixedly provided inside the outer shell 1, a telescopic rod 8 is fixedly provided at the bottom of the inner bin 7, a floating ball 9 is provided at the upper end of the telescopic rod 8, a top block 10 is fixedly installed at the upper end of the floating ball 9, a sealing member 11 is movably connected inside the outer shell 1, a flange 12 is fixedly provided above the outer shell 1, a threaded groove 13 is provided on the upper surface of the flange 12, an external thread 14 is movably connected inside the threaded groove 13, an exhaust net tube 15 is fixedly installed above the external thread 14, an upper cover 16 is movably connected above the exhaust net tube 15, screws 17 are passed through the upper four sides of the upper cover 16, the external thread 14 below the exhaust net tube 15 is provided, the exhaust net tube 15 can be easily disassembled and replaced on the flange 12, and the upper cover 16 is fixedly assembled on the exhaust net tube 15 by means of the screws 17, thereby improving the installability of the exhaust net tube 15, and the flange 12 is provided, so that the exhaust net tube 15 can be disassembled and assembled with the outer shell 1.

[0026] like Figure 1 and Figure 2 As shown, slide grooves 3 are provided on both side surfaces of the interior of the air inlet pipe 2, and a slider 4 is movably connected inside the slide groove 3. A filter plate 5 is fixedly installed on one side of the slider 4. Bolts 6 are penetrated on both sides of the air inlet pipe 2. Through the setting of the filter plate 5, the water entering the exhaust valve assembly can be filtered, so that impurities in the water are not easy to enter the exhaust valve, and the exhaust valve is not easy to be blocked by impurities, which ensures the service life of the exhaust valve to a certain extent.

[0027] like Figure 3 As shown, the telescopic rod 8 is arranged at the lower end of the float 9, and the telescopic rod 8 is fixed inside the inner warehouse 7. The float 9 is movably connected with the inner warehouse 7. When water enters the inner warehouse 7, the float 9 is lifted by the buoyancy of the water, blocking the top of the outer shell 1 and stopping the exhaust.

[0028] like Figure 3 As shown, the seal 11 is engaged with the housing 1 and is arranged in a U-shaped structure. The arrangement of the seal 11 enhances the sealing performance and prevents the internal water from flowing out and causing leakage.

[0029] like Figure 1 and Figure 5 As shown, the external thread 14 is fixed below the exhaust mesh tube 15, the upper cover 16 is arranged above the exhaust mesh tube 15, and the exhaust mesh tube 15 is threadedly connected to the flange 12 and the upper cover 16 respectively. Through the setting of the exhaust mesh tube 15, not only a large amount of gas can be dispersed and discharged, but also the sound of the gas exhaust airflow can be absorbed, which has a certain noise reduction function.

[0030] like Figure 1 and Figure 5As shown, a threaded column 18 is fixedly installed on the upper cover 16, and a hanging member 19 is movably connected to the outside of the threaded column 18. The setting of the hanging member 19 facilitates the hanging and transportation of the exhaust valve.

[0031] The practical working principle of the present invention is as follows: first, the sealing member 11 is engaged inside the outer shell 1, and then the flange 12 is threadedly connected to the outer shell 1, and then the exhaust net tube 15 is rotated and tightened on the outer shell 1, and then the upper cover 16 is placed on the upper cover 16, and the upper cover 16 is penetrated by the screw 17 to be fixedly connected with the exhaust net tube 15, and then the hanging member 19 is sleeved on the threaded column 18 and tightened, and then the sliders 4 on both sides of the filter plate 5 are aligned with the slide grooves 3 in the intake pipe 2, and then the bolts 6 are penetrated on both sides of the intake pipe 2 to limit and fix the filter plate 5. After the assembly is completed, the exhaust valve is installed above the pipeline, and when the exhaust starts, the gas enters the outer shell 1 through the intake pipe 2, and then the gas enters the exhaust net tube 15 for discharge, and the exhaust net tube 15 is a mesh setting, which can absorb It collects the sound of the air flow discharged by the gas and has a certain noise reduction function. When the gas is exhausted and water enters the pipeline, the water will enter the outer shell 1 from the air inlet pipe 2, and the filter plate 5 in the air inlet pipe 2 can filter the water entering the exhaust valve assembly, so that the impurities in the water body are not easy to enter the exhaust valve, and the exhaust valve is not easy to be blocked by impurities, which guarantees the service life of the exhaust valve to a certain extent. When water enters the inner compartment 7, the buoyancy of the water pushes the float 9 and the top block 10 to rise, so that the top block 10 is against the seal 11 in the outer shell 1 to prevent water from flowing out. When the water is drained, the float 9 loses the buoyancy of the water and will automatically drop, and then continue to exhaust. In this way, the use process of the exhaust valve assembly is completed.

[0032] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
